How do you express the 5-second rule in Chinese?

[geek_frappa]

In America, if you drop food on the floor, it's technically not dirty for 5 seconds.

it's called the 5-second rule.

.... in China, they say .. 吃了沒病 ... when food falls on the floor

does Chinese also have the 5-second rule?

wow~~ , Before I read your thread, I didn't know the 5-second rule for dropped food. There's an equivalent expression in my hometown--- 不干不净,吃了没病. hehe...

Maybe they have know the technical theory potentially?

Where did you hear that? I don't know of any such "rule".

Where did you hear that? I don't know of any such "rule".

It's not even a rule and is sometimes 3 seconds instead of 5. I don't know if it exists outside of the US, I learned it growing up in the US from other students (though I never adopted it, thank goodness).

Researchers say the 5-Second Rule probably only applies to tile and hardwood floors.

Food Science Professor Peter Blaschek said, "I think all bets are off when you're talking about something like carpeting. That's an entirely different story and we haven't done that study yet."

The five second rule only seems to exist in North America, I guess your floors are cleaner than those in Europe.

I only heard about the 5 second rule in China, and I'd thought it was specifically to help out those of us who hadn't quite mastered chopsticks yet.

that's absolutely correct. i am a native chinese speaker and i am now living in shanghai. the saying means that it is useless and even a little foolish to worry about the quality of the food. just eat it!
